A year after awarding landmark contracts to Boeing and SpaceX to build a new generation of human-rated space systems, NASA’s Commercial Crew Program has made great strides to re-establish America’s capability to launch astronauts to the International Space Station. Both companies are constructing the infrastructure needed to safely launch and operate crew space transportation systems. They also have offered detailed refinements to their designs and begun building the test vehicles that will be put through extreme analysis before their flight test regimens begin.
